The AD31 is a waterproof EC/TDS and temperature tester. The housing has been completely sealed against humidity.
All EC and TDS readings are automatically temperature compensated (ATS), and temperature values can be displayed in ºC or ºF units.
The EC/TDS conversion factor (CONV) can be selected by the user, as well as the coefficient Beta for temperature compensation.
The instruments can be calibrated at one point. Measurements are highly accurate with a unique stability indicator right on the LCD. The models are also provided with a low battery symbol which warns the user when the batteries need to be replaced.
The AD32P probe supplied with the meters, is interchangeable and can be easily replaced by the user.
The encapsulated temperature sensor allows fast and accurate temperature measurement and compensation.
Each meter is supplied complete with:
– AD32P EC probe
– 4 X 1,5 V batteries, button type
– User manual
